Kwinqanaba lokuqala le-frequency mediumumatshini wokuwelda indawo, ngenxa yempembelelo yoxinzelelo lwe-welding, iinkozo ezinezikhokelo ze-crystallization ezifanayo kunye nezikhokelo zoxinzelelo zibangela ukunyakaza kuqala. Njengoko umjikelo wangoku we-welding uqhubeka, i-solder joint displacement iyenzeka.
De i-solder joint displacement ayinakubuyiselwa, le nto ibizwa ngokuba yi-solder joint position accumulation, emva koko i-chear micro-cracks iyenzeka kwinqwelomoya ethile yokufuduka. Ekuqaleni kolu fuduso, i-microcracks kwi-weld nugget stop kwimida yengqolowa yeenkozo, kwaye xa i-deformation yeplastiki yendawo yeenkozo ezikufutshane idlula ixabiso elithile elibalulekileyo, iintanda ziqala ukwanda.
Xa uqwalasela icandelo lomnqamlezo wokwakheka kokuqhekeka kwinqanaba lokuqala le-weld nugget yomatshini we-welding we-medium frequency spot welding phantsi kwe-microscope, unokubona ukukhutshwa kunye nokukhutshwa kweenkozo. I-extrusion kunye ne-extrusion ayihambelani nolwalathiso lophuhliso lwee-macroscopic cracks, kwaye ubuso obubi bubonakala kwimilo yomgca ongcolileyo.
Kwinqanaba lesibini, inkqubo yokusasaza kokuqhekeka ibandakanya umjikelo wokwandiswa komphezulu wemigca ebambekayo, ukukhula kokuqhekeka kunye nokuvalwa kokuqhekeka okubangelwa luxinzelelo, kwaye yanda kwicala eliqhelekile kwicala lesenzo somthwalo. Xa ukuqhekeka kusanda, ukutyibilika kwe-ductile kunokubonwa kwindawo yokuqhekeka. Imilo, imigca eqaqambileyo ejikelezayo ephantsi kwe-microscope.
Inqanaba lesithathu lisondele kwintshabalalo. Njengoko uqhekeko lusanda, uxinezeleko oluphezu komhlaba lugxininiswa ukuze lwandise, yaye umlinganiselo wokwandiswa uba ngokukhawuleza nangokukhawuleza de uqhekeko luphulukane nokuzinza luze lubangele umonakalo kwisakhiwo.
